I have received from Pollin (http://www.pollin.de/) some part, including these two golden 377 TO-3 from Motorola.

I suspect that the 377 is a date code (March 1977) and the part number is not there. Probably a special run for a big customer and perhaps they didn't want part numbers in the same way that companies grind the part numbers off the tops of ICs now.

You can check if it is a transistor, thyristor, triac, etc but you can do better with modern devices if you are building something.

PFFT, sometimes those so-called "component testers" are useless. Try just a standard diode tester to find the junctions, but you'd need a curve tracer to really know more about it. If you don't see any junctions, it's either dead or it might not be a normal semiconductor and it could be some sort of sensor or switch like a thermal cutout.

I've seen these connectors plenty of times, but don't know what they are called or who makes them.

Hoping for a cheap Aliexpress source, since I'm after about 150 of the connector shrouds and pin sets to match these connectors on some stepper motors.The motor connector pins are standard 0.1" spacing, pins are 0.6mm square. But the pin length is about 4mm. Much shorter than the usual 0.1" pin headers.

It is typically quite useful to include the PITCH (distance between pins in mm or inches) when asking questions about connectors.If for no other reason than to provide some sort of scale so we know what we are looking at.Withholding the identity of the "device" is not typically in your best interest.

I will measure that later, the pcb is part of the battery charger in a CityEL (electric vehicle) it has two big heatsinks that are connected to the battery voltage which means that i need to disconnect the batteries, bms e.t.c. before i can remove the board. I Couldn't open the vehicle this morning, the lock is frozen, i will try to do some measurements later.

I was hoping that someone knows which type of connector this is. It is easier to find a maching connector with some keywords like for example JST (which it isn't). I've attached a bigger picture of all PCBs under the seat.

Top left: DC-DC step down converter for all devices that require 12V Right side: Charger PCB with the connector i'm looking forBottom left: Part of the BMS (Power Supply, relais for controlling the charger, current limiter for the drive motor)

The connector on the bottom is not used anymore, it was used for the old current limiter board.

Edit:I managed to find a similar conector in the pile of spare parts i got with the vehicle, the pitch is about 7mm, and the connector is about 5.5cm wide. Still can't open the vehicle i'm not sure if the connector does fit.

Hi! Plowing through the pile of RF junk, I have stumbled upon these. Could you please help me identify those two suckers?

The first one is the AD42866. The only mention of them is on this fake datasheet site, where you can only read it is (probably) a "Serial Input 16-Bit 4 mA-20 mA, 0 mA-20 mA DAC" - which mght be true. The 9752 is the date code, definitely not a part no. Looking for a datasheet seem like looking for unobtanium.

The second chip is really I-don't-have-any-clue-what-that-is-or-does type. There is an RF output at the bottom going to the MMIC amplifier, input at the top. There are also four digital lines going to the chip. The best of my guess is a programmable gain amplifier or attenuator. Is the last part in the IF receiver chain, the IF being likely 13.0MHz (?!), as it goes through a "E13.0A" ceramic filter before this IC.

I have quite a lot (~10pcs) of these same RF boards, all of them contain the W1466 IC, but only some of them contain the AD42866. I was just curious if those ICs are any kind of interesting to reuse in some projects.

Anyway not that curious that I would write emails to the companies that made them. They would not tell me anything about it either. Such big corporates doesn't give rat's ass about nosy people like me.
